Thing is though, look at places like France. Paintball's going from strength to strength, with a massive influx of players... I don't deny UK paintball does *appear* to be on the decline, obviusly for the reasons mentioned above. However, I don't think this has anything to do with the death of 7-man or format change.
I'd point the finger at the US. The NXL is by far the biggest, most competative, and best league there is, the NPPL plays second fiddle. Everyone is just trying to emulate that sucess...
